.liquid fuel-so as to assure quick levaporation of such fuel and proper operation of the engine at any tem-l perature, and thisv without resort to the use of piping, mixing apparatus and the like. s Another object of the invention is the provision in an. internal combustion engine ci simple and eicient means for regulating the speed of the engine, and:

Another object is the provision in an internal combustion engine of compact and eicient means through the medium of which the engine may be readily reversed when necessityemands.l

Other advantageous features peculiar to my invention will -be fully l.understood from the following description and` claims when'the same are considered in within the same.

connection with the accompanying drawing forming part of this specification, in which:

Figure l is a longitudinal sectional view of the engine' constitutiugthe present and preferred embodiment'oi niy invention with someof the parts 'in elevation. Fig. 2 is a detail transverse section taken through the reversinggear of the engine inthe plane indicated by 'line-2 2 of Fig. 1. y

Referring by letter to the said drawing: A is the casing of my novel engine which may be arranged horizontally, vertically or at anangle of inclination, as required.

B is al transverse shaft journaled inopposite side walls of the casing and having a crank C movable D isI a retilinearly -movable piston connected through a pitman E with the crank C and arranged to divide the casing into a' crank chamber F and an explosion chamber G; and E is awater. jacket surrounding the explosion chamber G and designed to prevent undue heating thereof in the ordinary well known manner.

In addition to the crank chamberF and the explosion chamber G, the casing A is provided with a mixing chamber I, a valve chamber J, a port K intermev diate the valve chamber J and the inner. portion of the explosion chamber G, a portL intermediate said valve chamber J and the atmosphere, and a chamber M\ arranged at the outer side of the head of the explo- -sion chamber and communicating at one end with the mixing chamber I. The chamber M is connected by ports N with the atmosphere, and the said ports N are suiiicient in number and size-to avoid the making of noise when air is drawn through the same and into the chamber M on the outstroke of the piston D, as will hereinafter be more fully explained. The air drawn as stated into the chamber M will tend to prevent undue heatingof the. cylinder head and will become heated by reason of'its proximity to the head with the result that .when it reaches the mixing chamb`er'I it will be in a condition to accelerate evaporation of low grade liquid fuel and thereby assure proper operation of the engine at any temperature.

P is a fuel supply conduit adapted to be connected with a suitable source of supply and leading to a taper bore Q which communicates at its reduced end within the chamber I. R is a. taper valvewhichis arranged in the taper bore Q and is backed by a spring S which in tum is backed by a plug T. U is a port intermediate the mixing chamberl and the valve chamber 'J and W is alvalve adapted to normally close the said port U and control the supply of explosive mixture 'to' the chamber G. The said valve W is provided with a stem X, and on said vs tem is aplate or other abutment Y between which and the casing a spring Z isinterposed;'said spring having for its oflice to normally hold the valve W against and return said valve to its seat. The abutment Y is arranged to engage the taper valve R, andhence it follows that when the valve W- is drawn away-from its seat by the suction created on the outstroke of the piston D, the valve R willbe opened against the action of the spring S with A the resultthat liquid fuel will be drawn into the chamber I and there commingled with the heated air from the chamber M.

- In order that the extent to which the valve W is vopened may be regulated with a view of controlling the speed ofthe engine, I provide the mechanism shown at the left of the drawing. This mechanism comprises a head a on the outer end of the valve stem `X, a washer b of leather or other suitable soft material mounted on lthe valve stem at the inner side-ofthe head and designed to prevent noise when the valve W issuddenly opened or drawn away from its seat, ay

vthreaded plug c arranged in afcorrespondingly threaded aperture d in the casing, and a rotary and endwise movable sleeve `e disposed in the said plug c. The said sleeve is engaged with the plug, preferably .through the medium of a fast-thread f, and hence it will be apparent that when the sleeve is turned in one direction it will be quickly moved outward or toward the head i aand when it is turned in the opposite direction itwill be moved at a similar rate df speed inwardly or away from the said'head a. The head a or ratherv the washer b bringing up against the outer end of the sleeve e limits the' extent to which4 the valve Wopell, and

spondingly increased. The sleevec maybe turned by hand through the medium of a lever g or other suitable means, or if preferred said sleeve may be `connectedwith and movedrtlirough the medium Vof suitable gine.

governor mechanism deriving motion from thevcrank shaft B or any other suitable working part of the en- By reason ofthe taper valve `R being openedV bythe abutment Y on the stem of the valve W,the opening of the saidvalve R always corresponds in extent to the opening ofthe valve W which assures the supply of a proper quantity of lliquid fuel-tothe heated air in theand having a stem h guided in the casing yAv and lterminating in a threaded portion 4Bfis a rod guided in a chamber j of the casing and having a tubular portion K2 and also having a threaded bore Z receiving and engaging the ,threadedend of the valve stem. y u,

C is an anti-friction roller carried on ,the end of the rod B. l I y D is a coiled spring anaifged in the chamber j and the tubular portion of the rod B and interposed between the casing A and Isaid rod so as to return the valve A to and normally hold the same against its seat; and E is a set screw which bears Ain the rod B and against the threaded end ofy thefvalve4 stem so as to prevent casuall movement of the one with respect to "the other, and is disposed and movable in a longitudinal H is .a cam fast on the shaft kGl and having an I carrying a-lateral taperedA plug J. K is aspur gear through which the shatG is adapted to be moved cndwise for a purpose'presently set forth; said gear K having tapered sockets L arranged about the proportional distance illustrated apart, one of said pockets shown in Fig. l andthe other in Fig. 2, andalso having lateral abutments Mkin close proximity tothe sockets Lv, and N and P are gear `wheels which in connection With tho gear where-.l l are adapted torreduce the spoed of the crank4 shaft B- from two to ,onethat is to say, to assure the crank shaft turning through two complete rcvolutiouswhilc the shaft G is turning through one revolution. K y l In the practical operation of my novel engine,A itwill be observed that on the outstroke of the piston D the suction creatori in the chambortG will operate to open thovalvoW and the taper valve R, and draw atmospheric air through the chamber M into the mixing chamber l, and also draw a charge of explosive mixture from the said chamber I into the explosion chamber G, On the inwardstlokc of the piston l) the said charge will be lcompressed until the crank (l passes the dead Vcenter whenthe ycharge will be ignited and the piston forced outwardly to repeat the operation before stated. At the proportime subsequent to the explosion of theI charge yof explosivo mixture the cam H operating against the anti-friction roller C will open the valve. A and assure the proper discharge of the products of combustion from the chamber G;

run forward. When, however, the shaftG is' moved -endwise, by hand or through' the medium of any suitable mechanism, it will be observed that the taper p lug Il" will be Withdrawn from the taper socket L in i which it is shown as resting. The shaft G may'thcn be turned to'carry the taper plug J" Ainto alinement with the othery socket-L, after which the shaft is` moved endwise 'inthe opposite direction to that first mentioned so as to positionthe plug in the latter Asocket L and-the arm I againstfthe abutment lM adjacent to the saidsocket: l With the cam-H thus positioned, relative -to the Wheel K andthe anti-friction' roller C the engine will' obviously run in a reverse direction or backward.

When the cam H is turned in the manner and for the purpose stated, the abutments M will preclude the plug J moving past the sockets L. and in that Way will assure quick engagement'of the plug withy the gear K I In addition to the features hereinbefore described, the casing A is provided Witha drain aperture A2 leading from the mixing chamber I. This aperture A2 has for its purpose to drain? the said chamber 'I of'liquid l fuel, this -in orderV toprevont accumulation of liquid ingoftheengine. f l v vThe chamber I is, by preference, formed in a bushing disposed in the casing A as illustrated.

yThe openings a and b in communication with the valve chamber .I are for the reception of the members of an igniting mechanism which per se forms no part of my present invention. The said members which are lettered c and d are designed to be electrically connected with a source of electric energy notl shown. I desire it distinctlyunderstood, however, that I'rneiely illustrate the members c and d in order to complete the engine, and that any other igniting means may be employed without involving adeparture from the scope of my invention. v` Having described my invention, what I claim an desire to secure by Letters-Patent, is:

` 1. In :m internal combustion engine, the combination of a pistou, a cusingcontaining' thepston and having an explosion chamber, a mixing chamber, a conduit tapered in a .fuel in the chamber I and interference with the startydirection away Vfrom the explosion chamber and communieating atits reduced end with the mixing chamber and arranged to be connected with a source of fuel supply, a conduit for supplyingr the mixing: chamber with air, a valve arrangedy to control communication between the mixing lcharr'iber and the explosion chamber and having a stem on the stem of said first mentioned valve, avthreaded sleeve surrounding the stem of the irst mentioned vaive and' arranged in and engaging a correspondingly threaded bore in the casing ;,s'aid sleeve being adjustable in thedi-l rection of its length, and a headon the outerv end of the valve stem. l ,i
